WARREN L. MCCORMICK, OF SAPULPA, OKLAHOMA.

PIPE-COUPLING.

To all whom it may concern:

Be it known that I, IVARREN L. MCCOR- 11101;, a citizen of the UnitedStates, residing at Sapulpa, in the county of Greek and State ofOklahoma, have invented certain new and useful Improvements in Pipe-Couplings, of which the following is a specification.

This invention relates to certain new and useful improvements in theconstruction and operation of pipe-couplings and has for its object theconstruction of a coupling which will permit T and L joints to beuncoupled without disturbing the lineof pipe or cutting the pipe as isnow necessary.

In the accompanying drawings Figure 1,1s an elevation of my improvedcoupling showing a section of pipe in place in either flange. Fig. 2, isa front elevation of one of the flanges. Fig. 3, is a longitudinalcentral section of the complete coupling. Fig. 4, is a longitudinalcentral section of the ball.

Referring to said drawings by numerals; 1 represents av spherical memberprovided with suitable threaded openings 2, preferably three in number,communicating as shown in Fig. 3. Brass facings or bushings 3 areprovided at each opening and likewise on the blank face. The object ofthe facing on the blank face being to provide a more secure oint whenmaking an L joint. Brass facings 3 are adapted to be engaged by acounter-sunk portion 4 of the flanges 5 to form a more perfect seat orjoint.

Flanges 5 are provided with a central opening 6 and a raised portion 7,surrounding said opening, said portion being interiorly threaded toreceive the end of a pipe. Said flanges are further provided, near theouter edge thereof, with perforations 8, spaced 90 degrees apart, toreceive bolts 9 for the purpose of binding said flanges to Specificationof Letters Patent.

said ball 1. In one of said flanges a sunken portion 10 is provided toreceive the heads of bolts 9 and hold the same against turning, therebyfacilitating the tightening of said bolts.

In practice my invention is utilized as follows: When a T joint isdesired the ball 1 is screwed on the end of the pipe forming the stem ofthe T, the opening opposite the blank face being utilized for thispurpose, the flanges are then screwed on the ends of pipe forming thecross bar of the T, the bolts inserted and the flanges drawn snug to thefacings of the other two openings. To make an L joint one of theoppositely disposed openings is plugged, the ball screwed on to one endof pipe, a flange screwed to the other end of pipe, the other flangeplaced in position on the blank face, the bolts inserted and the flangesdrawn together.

Having described my invention, what I claim as new and desire to secureby Letters Patent is:

A pipe coupling comprising a spherical member provided with radialopenings, bushings fitting said openings and having their outer endsprovided with outturned annular flanges, flanges for engaging oppositesides of the spherical member and pro vided with central openings forthe reception of pipe ends, said openings being surrounded bycountersunk portions for the re ception of the end flanges of thebushings, and means for clamping the oppositely disposed flanges to thespherical member.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.
